can somebody please tell me if there is any difference in the normal adsense code and adsense code for feeds( rss, xml). If yes, then please tell so that i can make sure which site is using adsense for feeds one more thing, is there any way to know from where a particular site has taken their content for feeds?? One thing more, as now the adsense sign up for feeds is not available, so can i do this thing. I divide my page in two vertical parts using tables... left part will be smaller...and then i put my normal adsense code in the left part and display the feed content in the right part.... so will the ads be contextual???
AdSense for feeds works by embedding images into the feed. When the image is fetched by the feed reader, an image is dynamically generated from a text ad. No JavaScript runs. Since feed readers do not run JavaScript as a rule, embedding the standard AdSense code into your feed will achieve nothing, that's why they developed this different technology for feeds.
thanks Eric. But what i really want to ask is: If i am using feed reader on my site( to place other's content on my site) then can i use the normal adsense in my site.. will they provide contextual ad. and the other question is how can i come to know.. from where a particular site it taking its feed
Your best bet right now is to not put your complete articles into the feed -- add a link to the bottom of the feed to get users back to your site (and your ads).
As long as the content is being generated into the page on the server and not on the client, then yes. The key is that Google's crawlers must be able to see the content. If the content is inserted into the page by some JavaScript code running in the browser, the crawler won't see it and won't be able to use it to target the ads. A lot of "scraper" sites that display AdSense ads work the way you're envisioning things.
